检查24 V DC和230 V AC之间的间隙和爬电距离是否符合EN 60950或UL 950。如果没有,则在操作员面板中输入一个单独的24 V装置。40 3BSE069463-600 D版第7节附加安装提示电隔离如果24 V DC和230 V AC的继电器触点之间有相当大的距离,则可以对所有馈电使用相同的24 V设备。见上图中的3。将24 V馈线上的0 V接地,参见上图中的4。这有三个优点:•提高了安全性。在0 V(24 V)和230 V相位之间发生故障连接或短路时,24 V馈线不带电。•24 V馈线上的瞬变连接至接地。•24 V供电处于相对较高水平的风险 Check that the clearances and creepage distances between 24 V DC and 230 V AC fulfill EN 60950 or UL 950. If not, input a separate 24 V unit into the operator panel. 40 3BSE069463-600 Rev D Section 7 Additional Installation Tips Galvanic Isolation If there is a substantial distance between the relay contacts for 24 V DC and 230 V AC, it is OK to use the same 24 V devices for all feeds. See 3 in drawing above. Connect 0 V on the 24 V feed to the ground, see 4 in drawing above. This offers three advantages: • Safety is increased. The 24 V feed is not live in the event of a faulty connection or short circuit between 0 V (24 V) and 230 V phase. • Transients on the 24 V feed are connected to the ground. • No risk that the 24 V feed is at a high level in relatio
